Title: Standing wave interferometer for measuring optical path differences
Inventor: BUCHNER HANS
IPC: G01B9/02
Filed: 1983-03-24
Granted: 1986-04-30
Abstract: The invention relates to a standing wave interferometer for measuring optical path differences in which a standing wave is produced between a monochromatic light source and a reflector. The displacement of the bulges and nodal points of the standing wave due to displacement of the reflector is sampled by a sampling normal inserted into the standing wave and having two photodetecting layers at a mutual space of kx lambda /8, k being any desired odd integer. The sampling signals are fed into an electronic evaluation unit where these are processed. The measuring object, when having a well-reflecting surface can be the reflector itself, without the necessity of adjusting the same accurately to the incident light beam.

Title: Time clock system
Inventor: WEXLER JOEL S
IPC: G07C1/10
Filed: 1986-11-18
Granted: 1990-01-04
Abstract: An employee clock system is disclosed which has a central data collector device connected to a plurality of remote satellite time clock stations. The timekeeping function is performed at the central data collector, and communication between the data collector and the time clocks takes place over communication channels wired in a spoke, rather than in a loop, configuration. The system permits use of a supervisor's card to clock in for another employee, while preventing non-supervisory employees from doing so. The central data collector collects employee attendance data from all the remote time clock stations, puts it in a form usable by a general purpose programmable computer, and sends it to the computer for use in preparing a payroll, Battery back-up is provided to permit employees to clock out in the event that the plant is closed because of a power failure.

Title: Blemish concealment in video signals
Inventor: MAY ROBERT EDWARD
IPC: H04N5/213
Filed: 1996-07-31
Granted: 2000-03-22
Abstract: A video signal 21 is input to a motion-compensated median filter to produce a preliminary blemish-concealed signal 23. The preliminary signal and the original input signal are passed via appropriate delays to respective inputs of a selector switch 31 and to a side chain circuit. The selector switch is controlled by the side chain circuit output and the selector switch output 22 forms a final blemish-concealed video signal. In the side chain circuit a difference signal C is generated to indicate differences between the input signal and the preliminary signal. The difference signal C is processed in two parallel circuit branches to remove differences having gently-sloping edges and differences corresponding to similar-sized differences in similar areas of adjacent frames, which are likely to be motion artifacts. The modified difference signals from each circuit branch are combined in an AND gate 95 to generate a control signal, which controls the selector switch 22 to output the original input signal except in image areas where the side chain processing indicates that a blemish is present. <IMAGE>

Date Jun. 24, 1993.A plasma torch is designed for energy supply for example for chemical processes. The plasma torch comprises at least three solid tubular electrodes (1, 2 and 3) located coaxially inside one another. The electrodes (1, 2, 3) can be moved axially in relation to one another. They are preferably electrically insulated (5, 6, 7) from one another and have connections for electrical power (8, 9, 10). When three electrodes are used, the middle electrode (2) is used as an auxiliary electrode or ignition electrode. It is then coupled with one of the other electrodes (1). The distance to third electrode (3) is adapted to the working voltage in such a way that a jump spark is obtained when the working voltage is connected. During operation the auxiliary electrode (2) is withdrawn from the plasma zone thus preventing it from continuously forming the foot point of the arc.

Abstract: Dimethyl carbonate is prepared by means of a continuous process:   by feeding, to a reaction chamber, methanol, carbon monoxide and oxygen, to a liquid reaction mixture with substantially constant composition and volume, containing methanol, dimethyl carbonate, water, and a copper catalyst; vapourising from the reaction mixture a stream of methanol, water and dimethyl carbonate, which is developed together with the carbon-monoxide-containing gas stream; and recovering water and dimethyl carbonate from said vapourised mixture, in amounts substantially equal to the respective amounts thereof which are formed in the reaction chamber and recycling the other components.   The process, which is essentially characterized in that in the liquid reaction mixture a methanol concentration and a water concentration are maintained which are respectively equal to, or higher than, 30% by weight, and equal to, or lower than, 10% by weight, makes it possible dimethyl carbonate to be obtained with an improved productivity.

Title: Copper surfaced building plumbing and sheet-metal work sheet - comprising centre ungalvanised sheet steel layer coated with soldered copper foil
IPC: B21C/
Filed: 1975-03-18
Granted: 1979-11-10
Abstract: The purpose is to provide, at low cost, metal sheeting, for roof and rainwater guttering, drainpipes, roofing, sill cladding, other building constructions, tinsmithing, and plumbing uses, which is durable, rust and corrosion-resistant, and does not need to be painted, even where industrial gases are a hazard. This is achieved by the use of a load bearing centre layer of non-galvanised sheet steel, coated with a laminar-soldered sheet of copper foil on both sides, providing a sealed connection which completely protects the steel from atmospheric conditions. The sheet steel can be immersed in a tinning bath, and the prepared copper foil rolled straight onto it. This is much less expensive than copper sheeting of the same strength, with the same qualities.

Abstract: An appliance for treating teeth, such as human teeth, by providing them with a reinforcing acid-resistant layer of a tooth decay retarding agent. The appliance includes a vibrator for producing ultrasonic vibrations, this vibrator terminating in an elongated vibratory tip. A casing houses the vibrator and has a tubular open end region in which the tip is at least partly accommodated. This tubular open end region of the casing carries an elastic membrane wall which extends across the tubular open end region of the casing and through which the tip extends so that the tip has a free end situated outwardly beyond this elastic membrane wall. The elastic membrane wall fluid-tightly engages the vibratory tip while surrounding the latter, and the membrane wall maintains this fluid-tight engagement with the tip during vibration thereof. The tubular open end of the casing is adapted to be attached to a tray which has a hollow interior provided with a liquid vibration-transmitting medium, the tip piercing into the interior of the tray to engage the liquid medium therein when the tray is attached to the casing at the tubular open end region thereof.
